Clamping base

ABSTRACT

The present invention is a clamping base, including a body capable of engaging with and holding a camera, and a second wall portion capable of being detached from and engaged with the body. The clamping base further includes a moving portion. The moving portion includes a sliding rod and a first wall portion set at one end of the sliding rod. The sliding rod can perform a push-pull movement on the body and the other end of the sliding rod is set inside the body.

FIELD OF THE INVENTION

The present invention relates to a base for a camera; particularly, it relates to a clamping base capable of flexibly adjusting a holding position so that a camera can be easily installed on the clamping base.

BACKGROUND OF THE INVENTION

The base for holding the conventional web cams to an electronic device, such as a notebook, an LCD, and so on, is as follows: One means is to adapt the clamping force of a damper so as to clamp the web cam on the electronic device. Although the damper can be adjusted according to the thickness of the various electronic devices, large clamping force can easily cause the electronic device to break. Furthermore, the main drawback of the damper is that for those electronic devices with a greater thickness, the length of the two clamping arms of the damper must be increased. Another means is to adapt a base in a slight n-shape so as to utilize the fixed size of the opening of the base; the two opposite sidewalls of the opening press against the two sides of the electronic device respectively. The main drawback of the n-shape base is that because the size of the opening of the n-shape base is fixed, it is only useful for the electronic device having the same thickness as the size of the opening.

Due to the two conventional means being limited to the thickness of the electronic device, the inventor of the present invention provides an improved easily adjustable clamping base so that the web cam can be more easily installed on the base in accordance with the thickness of a variety of electronic devices.

SUMMARY OF THE INVENTION

An objective of the present invention is to provide a clamping base capable of being detached from or engaged with a camera.

Another objective of the invention is to provide a clamping base for a camera which can flexibly adjust the holding position in accordance with various thicknesses of electronic devices.

In order to accomplish the above objectives, the present invention provides a clamping base of a camera, including a body capable of engaging with and holding a camera, and a second wall portion capable of being detached from and engaged with the body. The body includes a pressing plate, wherein the pressing plate is used to allow the camera to be inserted therein, and thus to press against and hold the camera. The clamping base further includes a moving portion; the moving portion includes a sliding rod and a first wall portion set at one end of the sliding rod; wherein the sliding rod can perform a push-pull movement on the body, and the other end of the sliding rod is set inside the body.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows an elevational diagram of the clamping base and the camera before engagement, and FIG. 2 shows an elevational diagram of the clamping base and the camera after engagement. In FIG. 1, the elastic plate 21 of the camera 20 is inserted within the pressing plate 11 a (as shown in FIG. 3) of the clamping base 10. Refer to FIG. 2, when inserted, the elastic plate 21 is pressed against and held by the elasticity of the pressing plate 11 a so that the camera 20 can be stably disposed on the clamping base 10. The material of the pressing plate 11 a of the present invention can be made of a malleable plate, such as a plastic plate, or a metallic plate, etc.

FIG. 3 shows an elevational diagram of the base of the present invention. The clamping base 10 of the present invention includes a body 11, a moving portion 13, and a second wall portion 15, each being illustrated in the following context. The body 11 can be in a slightly rectangular shape. The top of the body 11 is disposed of a pressing plate 11 a, and the bottom thereof can be detached from or engaged with the second wall portion 15. Refer to FIG. 4A showing a cross-sectional diagram of a first way of engagement of the second wall portion and the body, and FIG. 4B showing a cross-sectional diagram of a second way of engagement of the second wall portion and the body, the second wall portion 15 can be engaged with the body 11 in two ways. In FIG. 4 a, the wallboard 15 a of the second wall portion 15 is close to the first wall portion 13 a. In FIG. 4B, the wallboard 15 a of the second wall portion 15 is far from the first wall portion 13 a (when compared to FIG. 4A).

FIG. 5 shows a positional diagram of a push-pull movement of the moving portion of the present invention. The moving portion 13 includes a sliding rod 13 b, and a first wall portion 13 a set at one end of the sliding rod 13 b. The other end of the sliding rod 13 b is set inside the body 11 so that the sliding rod 13 b is movable inside the body 11; in other words, the sliding rod 13 b performs a push-pull movement on the body. The main purpose of the push-pull movement to the sliding rod 13 b is to change the distance between the first wall portion 13 a and the wallboard 15 a. Refer to FIG. 6 showing a cross-sectional diagram of a camera with the clamping base of the present invention when the electronic device is in use. To use the camera 20 with the clamping base 10 of the present invention, the first wall portion 13 a and the wallboard 15 a are utilized so as to cross and press against the two sides of the electronic device 30. The electronic device 30 can be a notebook or an LCD. The distance between the first wall portion 13 a and the wallboard 15 a can be flexibly varied by moving the sliding rod 13 b, or by changing the combination of the second wall portion 15 and the body 11, as can the crossing and pressing, in accordance with the variety of electronic devices so as to hold the camera 20 with the clamping base 10 on the electronic device 30.

FIG. 7A shows a structural cross-sectional diagram of the moving portion of the present invention when not in a pull-push movement, while FIG. 7B shows a structural cross-sectional diagram of the moving portion of the present invention after the pull-push movement. An elastic element 13 c, such as a spring, is provided through the sliding rod 13 b of the moving portion 13. The first wall portion 13 a can be tightly pressed against the electronic device 30 by the elasticity of the spring.

The clamping base 10 of the present invention allows the camera 20 to be easily held and detached at the same time. Furthermore, the clamping base 10 provides an extensible moving portion 13. Together with the various combinations of the second wall portion 15 and the body 11, the clamping base 10 of the present invention can hold the camera 20 on the electronic device 30 with any thickness. The clamping base 10 of the present invention can be adapted to any type of camera 20, such as a web cam, a digital camera, etc.
